Deputies were called to a home in Edgewood early Sunday for a report of a fight, but the two men involved were gone. A 20-year-old man was taken to Upper Chesapeake Medical Center with a stab wound to the chest and was later transferred to Shock Trauma in critical condition.

The sheriff’s office says witnesses told detectives that two men had an altercation around 3 a.m. Sunday and one of them was stabbed during a heated exchange two hours later.

Detectives arrested Christopher McCullough, 20, of Abingdon later in the day and charged him with attempted first-degree murder and assault. McCullough is being held without bail pending a hearing.
